V04-10: The Use of Color Segmented Fluorescence to Assess Ureteral Perfusion at the Time of Urinary Diversion
Minimally invasive cystectomy has led to significant improvements in morbidity and complications during the operation. Despite this adjustment there is still little that has changed the rate of ureteral strictures at the time of urinary diversion during cystectomy. We describe our technique and early outcomes using color segmented fluorescence during ureteral anastomosis.
From April 2017 through October 2017, all patients undergoing cystectomy had their ureters assessed with color segmented fluorescence prior to ureteroenteric anastomosis. If poor perfusion was encountered, the ureter was re-resected until good perfusion was seen. Intraoperative complications, urinary leaks and 6 week post operative renal ultrasounds were evaluated.
17 patients had colors segmented florescence during the time of anastomosis. During the operation five of 17 patients required re-resection of the ureter prior to anastomosis. The average resected length was 4.1 cm. There were no postoperative urine leaks. No patients demonstrated hydronephrosis on the 6 week post operative ultrasound.
Color segmented florescence appears to be a viable option when assessing the renal perfusion at the time of urinary diversion. Further follow-up and comparative analysis is required.
